Controllers (110-1, 110-2, 110-3) in a system (100) are associated with technical entities and are adapted to selectively execute tasks (A, B, C) in a primary mode (101) when the controllers interact with the associated technical entities with respect to the tasks, and to execute tasks (A, B, C) in a secondary mode (102) when the controllers do not interact with the associated technical entities with respect to the task. The system distributes task instructions of a first task (A) to a first controller (110-1) that is configured to execute the first task in the primary mode (101), and to distribute the task instructions of the first task to a second controller (110-2) that is configured to execute the first task in the secondary mode (102). The system distributes task instructions of a second task (B) to the second controller that is configured to execute the second task in the primary mode. The system is further configured - upon non-availability of the first controller - to switch the second controller from the secondary mode for the first task to the primary mode for the first task, while the second controller is adapted to continue executing the second task in primary mode. |
